The new style Tiagra 10 speed chainset, designed to work with HollowTech II type bottom bracket cups, takes many features from the pro-level equipment such as the 4-arm crank and the grey anodised finish delivering unbeatable performance.

good value
not too much heavier than ultegra and for the price I cant fault it as can not even buy a single chain ring for the price I bought a brand new chainset.

Great value chainset
I swapped a worn out 105 compact chainset for this 52/36 Tiagra version and it really is the business. Great value and performance. Highly recommended

Great product
Replaced my old chainring and immediately noticed the improved difference.

Works perfectly
Arrived by DPD when they said it would. It costs a bit more for next day delivery but you get a 1 hour time slot so you can plan your day. Chainset and BB installed ok. Works fine as expected.

Replaced my old 9-speed Tiagra
Replaced old 9-speed chainset with this one. Works perfectly and cheaper than the current 9-speed Sora.

Works with 8 speed drivetrain
Upgraded from an FSA Tempo 50-34 8 Speed crank & chainset. Coupled with the compatible Tiagra BB-RS500 bottom bracket, this chainset works really well with the 8-speed chain and feels so much better than the existing square tapered bottom bracket; smoother and solid.

Slick shifting
Bought this as there is no 52/36 in the 105 range to replace my 50/34 105, the Tiagra is very smooth changing and just as good as the 105 chainset (IMO)

Great priduct as expected from Shimano.
Easy to fit and at this price, you can't go wrong.

great value for money crankset
Great crankset, replaced an old fsa set with this and a new BB and noticed an instant difference, lighter and stiffer and it looks good so everyone's a winner!

Good quality
It is not worth changing worn out FSA chainrings when you can get this at this price. Shift quality is great although to be fair, I guess the FSA chainset that was on had degraded with the wear. Anyhow. I'm very pleased with this.

Great new design, Top Shimano quality
The new design and finish look great for this compact crank set. I matched it with my installed Dura ace BB although I imagine any 24mm ID external BB would work. Very stiff, spins and shifts smooth and confidently every time. Only con is it is a little heavy at over 900 gms with out a BB but still well worth the price. I don't usually order from over seas but I can't find this stateside yet and Wiggle has the best price with free shipping!

Excellent Piece of Kit
Don't be put off with the fact it is Tiagra. Fantastic performance for a price is that unreal. Previously had an Fsa crank and like most experienced significant problems, this so far is proving to be much better. May even race on this

Get value again from wiggle
Looks great and excellent price! Replaced my old version and bike look 100% better

Answers

Having purchased several bikes, I've never been asked what crank arm size I need. Is there a typical / default size that I should buy or alternatively, from which point do I measure the size of the arm?

Answers

Answer:

You can measure the crank arm length from the centre point of the bottom bracket axle to the centre point of the pedal axle holes on the crank arm itself. Typically, most riders of an averaye height of around 5' 10" - 6' 2" would find a crank arm of around 172.5mm - 175mm would be suitable, although it can also come down to personal preference.

i have always used sora, tiagra and 105 components with replaceable 5 arm chainrings. this may be a silly question but can the rings of this set be actually replaced or do i need to buy the whole new chainset once the cogs are worn out?

I struggle with hills and so think it ideal to change the front chain set from 53/42 to this one. Can you give me guidance - is this suitable/compatible with the FOCUS CULEBRO or can you suggest a suitable/compatible (reasonably priced) alternative please?
